High Precision Q195 / Q235 Straight Seam Welded Tube Mill Line ZG165

ZG series high frequency straight seam? welded tube machine technical accessory

?Machine type: ZG165 ?

Production capacity:

?Production working flow:

Raw material (steel strip coil) →decoiler→flattening→powerful leveling →shear and butt-welder→horizontal type accumulator→passively leveling→forming machine→high frequency welding →remove the burrs outside→eddy current flaw detector→spraying cooling →sizing machine→straightening→fixed length cutting →run out table→finished tube

?Each part of machine introduction

The function of this part is to separating the steel strip coil and become to the raw material to roll forming . The steel strip coil will be brought in to the below of the double-drill uncoiler, hydraulic cylinder support the steel strip coil to the centre of the double-drill uncoiler , double-drill uncoiler began moving to hold the steel strip coil, coil car? fall off by hydraulic cylinder and go back.

Flattening and powerful leveling machine

The function of this part is to separating the front head of steel strip on the uncoiler,also reversed bending the steel coil head to adjusting it’s character of inner curl. Steel strip will enter into the flattening machine by dynamic rubber roll. Flattening machine equipped with one set of pinch roll device and five roll leveling device ,there is one pairs centring device in front and behind it.

(Flattening machine)

Shear and butt-welder machine

The function of this part is using hydraulic knife to cutting the irregular part in the front and end of the steel strip through the motor controlled by the human. Adjusting the size of the welding seam, translation hydraulic cylinder moving it to the welding position, two welding platen pressing it than moving the welding gun to the position of welding seam. Opening the motor ,welding and connecting two steel strip by using carbon dioxide arc welding ,polishing and flattening the welding seam by human, so the machine can working continuous. Shear and butt-welder is consist of :electric control operating table ,hydraulic station,welding machine,pinch system,lathe bed system(lathe bed and washer adjusting device),centring system(steel strip end fixed and front head of steel strip translation device ),crane system ,cutting system(cutting device and cutting platen) and welding system(welding tractor and welding platen).
